#

Let p be an unspecified directory path suitable for temporary files.

2

#

Effects: If exists(p) is false or is_directory(p) is false, an error is reported ([fs.err.report]).

Returns: The path p.

The signature with argument ec returns path() if an error occurs.

[Example 1:

For POSIX-based operating systems, an implementation might return the path supplied by the first environment variable found in the list TMPDIR, TMP, TEMP, TEMPDIR, or if none of these are found, "/tmp".

For Windows-based operating systems, an implementation might return the path reported by the Windows GetTempPath API function.
